By now, the decision is in: the $329 Ryzen 7 3700X is a wonderful CPU that competes properly in opposition to the $385 Intel Core i7 9700Ok in gaming and blows it out of the water in multi-threaded content material creation duties like video rendering or streaming. That’s helped the 3700X change into the most well-liked processor at one German retailer and result in AMD outselling Intel in stories from Korea and Japan. But how does the Ryzen 9 3900X fare? We’ve examined it in opposition to Intel’s high canine, the Core i9 9900Ok, to see which firm claims the general PC gaming crown.
First of all, let’s talk about what we’re coping with. The Ryzen 9 3900X is a fully-enabled Zen 2 design, that means it contains 12 cores and 24 threads unfold throughout its two chiplets. That’s 4 extra cores and eight extra threads than the Ryzen 7 3700X, so we count on to see considerably higher efficiency in duties like video rendering that are straightforward to interrupt up and carry out in parallel. The flagship chip additionally contains a barely larger single-core enhance frequency than its mid-tier counterpart, which ought to translate into higher single-threaded efficiency too.
Compared to previous Zen and Zen+ designs, this can be a complete completely different beast. I/O is shifted to its personal die utilizing a mature 12nm course of, whereas every of the CPU chiplets makes use of a novel 7nm course of that enables for larger efficiency than previous generations whereas utilizing much less energy (and due to this fact producing much less warmth). This architectural shift is accompanied by a sequence of small however nonetheless vital modifications: the scale of the L3 cache has doubled to ameliorate latency points, a extra environment friendly department predictor is used and AVX directions are lastly dealt with correctly.
|Ryzen 9 3900X||Ryzen 7 3700X||Ryzen 7 2700X||Core i9 9900Ok||Core i7 9700Ok|
|Max All-Core Turbo||4.1GHz||4.3GHz||4.1GHz||4.7GHz||4.6GHz|
This all sounds nice, however it’s not clear simply by wanting on the spec sheet or studying the function record how these processors will truly carry out in video games, notably older titles that weren’t engineered to utilize so many cores and threads. The solely method to settle that is to run by way of a gauntlet of current and not-so-recent video games at completely different resolutions – in order that’s precisely what we have finished.
Before we dive into the outcomes, it is price briefly bearing on how we carried out these assessments. We arrange a brand new Windows 10 set up – together with the newest safety and AMD scheduler patches – on quick SSD storage, with a Gigabyte 2TB PCIe 4.0 drive provided by AMD for our Ryzen third-gen testing and SATA SSDs used on different platforms.
The Principal benchmarking was finished on the entry-level 190 MSI MPG X570 Gaming Plus, with supplementary testing on a high-end motherboard, the 450 Prestige X570 Creation, with each boards provided by MSI. While the Gaming Plus is the most affordable MSI choice for the X570 platform, the Creation board would possibly make sense for anybody contemplating heavy overclocking or utilizing a number of PCIe 4.0 units. That’s as a result of in addition to sturdy energy supply and help for excessive reminiscence overclocking past 4600MHz, the Creation board additionally contains lively chipset cooling and a full complement of PCI-e 4.0 lanes. There’s even a PCI-e 4.0 add-on card that enables for 2 additional M.2 drives to be linked. Meanwhile, second-gen Ryzen was examined on an ASUS ROG Crosshair 8 and the Core i9 9900Ok was examined on an ASUS ROG Maximus XI Extreme.
Cooling duties have been break up, with the Ryzen chips utilizing the outstanding AMD Wraith Prism air cooler that comes bundled with all Ryzen 7 and Ryzen 9 processors and the Core i9 9900Ok paired with a Gaming Storm Castle 240mm AiO. In every case, we used GSkill Trident Z Royal 3600MHz CL16 RAM supplied by AMD, a hefty 850W PSU and an open-air take a look at bench.
While gaming efficiency would be the focus right here, we would be remiss to not point out efficiency in content material creation duties like video rendering and transcoding. Our very personal Alex Battalgia has waxed lyrical in regards to the relative power of the 3900X in comparison with his earlier 1700X-powered workstation in terms of cranking out movies, however is there a noticeable hole between second and third-gen Ryzen as properly? And how do Intel’s chips stack up?
Once place we will go to get some solutions is Cinebench, a sensible – if restricted – benchmark that mimics a rendering activity in skilled video software program Cinema 4D. The outdated R15 model of the take a look at could possibly be accomplished by fashionable CPUs earlier than they reached their standard temperature limits, so the brand new R20 revision features a tougher workload which is extra reflective of sustained efficiency. Both single-threaded and multi-threaded assessments are provided, which permit us to get a way of how Ryzen has developed gen-on-gen in opposition to the backdrop of Intel’s providing.
The Core i9 9900Ok stays the single-core king right here, however the Ryzen 9 3900X is only a few factors behind thanks largely to the 21 per cent generational benefit we noticed for the 3700X over the 2700X. This shut end result means that the 3900X ought to stay aggressive even in older video games that have not been architected for contemporary methods, one thing you could not say of first or second-gen Ryzen, however we’ll need to see how these titles play out. The multi-threaded outcomes see the 3900X come out on high by 38 per cent, due to the larger variety of cores and threads AMD’s flagship chip is packing.
Video encoding in common open supply software Handbrake is an much more real looking instance, and that is the place we’ll flip to now. For this take a look at, we encoded the identical pattern video file utilizing the x264 (h.264) and x265 (HEVC) compression requirements on the Production Quality Standard preset at CRF 18. The Ryzen 9 3900X reveals the identical basic developments because the Ryzen 7 3700X, with a small enhance in h.264 encoding speeds and a serious uplift in HEVC encoding due to that higher AVX instruction dealing with we talked about earlier. The larger core depend places even the Core i9 9900Ok to disgrace, with AMD’s present primary client CPU main the 9900Ok by 37 per cent for h.264 and 25 per cent for HEVC – an excellent end result.
It’s much more spectacular while you have a look at the facility consumption figures, as measured from the wall through the HEVC encode take a look at. AMD’s 7nm chiplets propel the Ryzen 9 3900X to 9900Ok-beating ranges of efficiency whereas consuming a lot much less energy; we measured a most of 228W in comparison with 266W for the Intel system, a distinction of round 15 per cent.
|Ryzen 9 3900X||Ryzen 7 3700X||Ryzen 7 2700X||Core i9 9900Ok||Core i7 9700Ok|
|Cinebench R20 1T||514||494||408||520||498|
|Cinebench R20 MT||7032||4730||3865||5090||3922|
|HEVC Power Consumption||228W||152W||224W||266W||171W|
These are stable outcomes to say the least, however let’s not get carried away. Our ardour is testing in-game efficiency, and that may be a completely completely different kettle of fish from artificial benchmarks and content material creation workloads. AMD has all the time been aggressive in terms of getting work finished, however can they beat Intel at dwelling with superior gaming outcomes too and actually push the boat out?
To reply this query a technique or one other, we wanted to seek out vital – and repeatable – sport scenes that would present the variations between completely different gaming CPUs. This is more durable than it sounds, as CPU-limited eventualities are rather more prone to random interference from working system processes and easy run-to-run variance than GPU-bound conditions. Even with all issues equal, completely different sections of the identical one-minute take a look at scene can present Intel forward of AMD and vice versa. That’s why we suggest testing the video evaluate embedded above or at the least watching the real-time metrics as every take a look at scene performs out, as you will get a extra substantial understanding of those chips’ relative efficiency than you’ll from wanting on the common or worst one per cent frametime metrics in isolation. After combating by way of the bugbears and pushing again the discharge of this evaluate, we’re lastly able to share our findings.
We examined every sport at 1080p, 1440p and 2160p, utilizing the most effective client GPU in the marketplace: the Nvidia GeForce RTX 2080 Ti. The 1080p benchmarks replicate a high-end system aiming for very excessive frame-rates to make full use of excessive refresh price screens, though this does imply coping with the stutter that always accompanies CPU-bound eventualities. The 1440p outcomes might be related for anybody on the present decision “candy spot”, the place a mid-range to high-end system can obtain frame-rates in extra of 60fps and infrequently nearer to 120fps with out sacrificing visible constancy. Finally, our 4K outcomes signify what’s arguably essentially the most balanced situation, the place there is a respectable quantity of CPU overhead and also you’re extra prone to be GPU-bound outdoors of some esports titles.
